There are two types of wind in front of the car:
One is the wind generated by its own kinetic energy (relative wind). Where does this energy come from? It transforms itself into electricity. Do you want to convert it back into electricity? Isn't it a waste of energy to move around like this?
The second is natural wind from outside, which can be divided into three types: 1. Wind from behind 2. Wind from side 3. Wind from front;
1 can be used; 2 can also be used; 3 can be used, but the available power is estimated to be not very high. Think about how much power such a large wind turbine on the front of the car can generate?
The most important thing is that the first wind is the main wind of the vehicle. The second wind can be almost ignored and is not useful at all.
So, not to mess around and waste energy, in reality no one will install wind turbinese on the car.
Why do gasoline generators often stall automatically during operation?
Here are the following tips:
1. First press the pedal several times. , turn on the power and increase the throttle. Don't move, step on it as hard as you can, all the way.
2. When starting with your feet, lightly press the start lever. If you feel that the combination with the starter gear is becoming heavy, push the starter lever hard and at the same time release the oil from the starter. intermittent throttle to the right, then throttle immediately, which can help get started.
3. When it is difficult to start, lightly press the start lever several times without refueling, and allow a little oil and gas to enter the cylinder. When starting the engine, increase the throttle slightly. On the start lever, be quicke to respect the engine speed requirements when starting.
4. There is no need to squeeze the clutch when starting with the pedal. Simply shift the gear into neutral, turn on the key and quickly squeeze the start lever.
5. If it's a cold start, you need to pull the wind and start. You can also hold the clutch to start when there is a gear. However, for some small displacement horizontal cylinder engines. , it must be empty. It can only be started on foot.
Detailed information:
1. The degree of atomization of gasoline
If the gasoline sent into the cylinder is not well atomized and more than half of it vaporizes, the electric spark from a spark plug Classic motorcycle cannot ignite liquid gasoline, soCarburetor atomization is very important! In cold weather, the cylinder wall is cold. Once the atomized gasoline enters the cylinder, it condenses into small oil droplets when it meets the cold cylinder wall, thereby reducing the efficiency of gasoline atomization.
2. Gas compression in the cylinder
It is usually easiest to feel on a pedaling engine when the piston rings are worn and leaking and the starter lever has failed. depressed, you will feel that the engine has no compression force, the engine will be more difficult to start. In a four-stroke engine, the small throttle valve limits the engine's air intake and the engine's actual compression ratio is greatly affected. This is the four-stroke engine. The main reason why the normal working efficiency of the machine is not high.
Also during the boot processengine, closing the choke too tightly will reduce the intake air volume and affect the compression effect of the mixture.
3. Electric spark quality
AC ignition motorcycles have been in poor condition for a long time and the magnets on the generator flywheel are magnetically degraded, causing the charging coil to output at slow speeds when of starting the engine. Insufficient power causes the igniter to spark at high voltage, which is one of the main reasons why some AC igniters have difficulty starting.
A high quality DC ignition rarely exhibits this problem. Therefore, when the engine has difficulty starting, you should check whether the ignition system can still ignite and how strong the spark is. A relatively simple method is to perform an out-of-cylinder bypass test at the cylinder head of theengine. If you have difficulty starting, try putting a high pressure cap on the test spark plug.
It should be noted that because there is high pressure gas in the cylinder, the tested bypass gap outside the cylinder must be twice as large to be considered a gap reliable ignition in the cylinder.
4. Carburetor Type
Carburetor type is critical to the starting performance of the four-stroke engine. It is best to use a carburetor with a manual enrichment valve. One type of carburetor can enrich the oil without affecting the maximum air intake volume, which is very conducive to engine starting.
It is not recommended to use the starter frequently. Although the carburetor may also vent oil when the choke is used, limiting the amount of air entering the cylinder will affect compression pressure and suck in mist.d of fuel. The chemical state is also relatively poor.
Gasoline generators often stall automatically during operation. There are several reasons. One is lack of oil, the other is the oil circuit blocked, the third is the body temperature is too high. and the fourth is The load is too great. These situations will cause the gasoline generator to automatically stall during operation.
If the machine is not very old or old, it is recommended to replace the spark plug and carburetor. If it is certain that the spark plug is not the fault, it is recommended that the oil supply line is not slick and cleaned or replaced.

How to store gasoline generators when not in use used for a long period of time:
1. Drain all the fuelence in the fuel tank and carburetor;
2. Drain all the oil in the crankcase
3. The engine oil reaches the upper limit of the oil level on the oil dipstick;
4. Close the choke and pull the starter handle to where resistance is felt;
5. Clean the device, cover it with cardboard or a plastic cover to prevent dust.
